I would think that it could be pressed out very easily. There is nothing special about it, just a different shape. When I first started making these, I struggled with getting it to run/swim. I almost gave up on it. The problem was that I wasn't putting enough bend in the blade and the whole lure would roll. Once I figured that out, everything else was fine. I don't use split rings, I modified my mold to accept a .051 stainless connecting link.
Lakeland Incorporated makes a blade called a Royal Spinnerbait Blade. It has a very similiar shape and I have been thinking about ordering a few of them to see if they would work. Would sure be nice not having to cut and file them. One thing that I have found when cutting and bending some blades is that the chrome/silver plating will pop loose and flake off. The blades I use on this lure, (I call it a "Mini Swim") are from Barlows It is their premium blade. The company that manufactures them, does an excellent job of platiing them. I have yet to have the plating pop off one of these.
